(a) The optical link adapter enclosure is not fully sealed ; install it with
the CNC control unit in the fully enclosed cabinet.
(b)Ground the case using the case fixing screw of the optical link adapter.
(c) The optical link adapter is light, and it may not be necessary to mount
it with screws. However, keep it from coming in contact with other
circuits to prevent possible short–circuits. When mounting the optical
link adapter in a cabinet, attach it with an L–type fitting using the case
fixing screws (M3) of the optical link adapter.
L fitting
For making up an I/O Link using the optical link adapter, the following
parts are necessary:
1 Optical I/O Link adapter 2
2 Interunit connecting cable 2
3 Optical cable 1
D Relay with an optical fiber connection adapter
For the outline drawing of the optical fiber connection adapter, see
Appendix D.
NOTE
Optical fiber cables can be relayed only at are location.
When a high–speed optical link adapter is used, no optical
fiber connection adapter can be used.
D Maximum transmission distance with an optical fiber cable(s)
The table below shows the maximum transmission distance with an
optical fiber cable(s), which varies depending on whether a connection
adapter is used for a relay.
